Disposable funnel apparatus

Abstract

This disclosure pertains to a disposable funnel apparatus comprising a pair of sheets being fabricated from a flexible water impervious material. The sheets are disposed in overlying relationship and are joined together along portions of the marginal edges thereof. Intermediate said portions, a pair of open mouths communicate to a common internal passageway therein-between. One of the mouths has a large opening and is utilized to collect fluids therein. The other mouth, having a smaller opening, is utilized to dispense the collected fluid. The marginal edges comprising the larger mouth are convoluted so as to enable the entire assembly to be transformed from a two dimensional flattened condition into a functional three dimensional shape, when forced inwardly into the larger mouth.

I claim: 
     
       1. A disposable funnel comprising a pair of sheets, said sheets having a pair of outermost surfaces thereof disposed in overlying relationship to each other, said pair of outermost surfaces having congruent marginal edges, said marginal edges defining a pair of innermost surfaces, said innermost surfaces being disposed in touching engagement to each other, a first portion of one of said innermost surfaces fixedly secured to a first portion of the other of said innermost surfaces, said first portion of said one innermost surface and said first portion of said other innermost surface disposed adjacent a first portion of said marginal edges, a second portion of said one innermost surface fixedly secured to a second portion of said other innermost surface, said second portion of said one innermost surface and said second portion of said other innermost surface disposed adjacent a second portion of said marginal edges, a third portion of said marginal edges, a fourth portion of said marginal edges, one end of said first portion of marginal edges being disposed adjacent one end of said third portion of marginal edges, the other end of said third portion of marginal edges being disposed adjacent one end of said second portion of marginal edges, the other end of said first portion of marginal edges being disposed adjacent one end of said fourth portion of marginal edges, the other end of said fourth portion of marginal edges being disposed adjacent said other end of said second portion of marginal edges, said third portion of marginal edges defining a collecting mouth, said fourth portion of marginal edges defining a dispensing mouth, said marginal edges defining a substantially elongated shape, said dispensing mouth being disposed on one side of said elongated shape adjacent the other end thereof. 
     
     
       2. The disposable funnel as claimed in claim 1 wherein said pair of sheets comprises a waterproof material. 
     
     
       3. The disposable funnel as claimed in claim 1 further comprising excursions occupying a sub-portion of said third marginal edges, said excursions extending outwardly from the remaining portion of said third portion of marginal edges, said excursions being disposed into said collecting mouth maintaining said collecting mouth disposed in an open state. 
     
     
       4. The disposable funnel as claimed in claim 1 further comprising one of said pair of innermost surfaces and one of said pair of outermost surfaces being disposed on a unitary sheet, the other of said pair of innermost surfaces and the other of said pair of outermost surfaces being disposed on another unitary sheet. 
     
     
       5. The disposable funnel as claimed in claim 1 further comprising said pair of outermost surfaces being disposed contiguously to each other on one surface of a unitary sheet, said pair of innermost surfaces being disposed contiguously to each other on said unitary sheet, a fold line, said fold line being disposed intermediate said other end of said first portion of marginal edges and said one end of said fourth portion of marginal edges. 
     
     
       6. The disposable funnel as claimed in claim 1 further comprising said pair of outermost surfaces being disposed contiguously to each other on one surface of a unitary sheet, said pair of innermost surfaces being disposed contiguously to each other on said unitary sheet, a fold line, said fold line being disposed intermediate said one end of said first portion of marginal edges, and said one end of said third portion of marginal edges. 
     
     
       7. The disposable funnel as claimed in claim 5 wherein said marginal edges are disposed in mirror-image relationship about said fold line. 
     
     
       8. The disposable funnel as claimed in claim 1 wherein said third portion of marginal edges have a greater length than said fourth portion of marginal edges. 
     
     
       9. The disposable funnel as claimed in claim 1 wherein said dispensing mouth defines a smaller opening than said collecting mouth.
